Projecting confidence while singing involves finding your correct posture and maintaining it throughout a performance. If you maintain that posture and a calm expression even if you forget the words to your song, many people probably won’t even notice.
It's been seen many times: The performer is onstage making up the words, but he looks as terrific as if he’d intended to sing those words. By maintaining poise and posture, the performer projects to the audience that everything is fine and assures them that they needn’t worry, as if to say, “I'll get back to the original words in a moment.”
The performer also walks away feeling good because he stuck to a basic singing rule: Good posture enhances good singing.
Projecting confidence onstage is important because you want to feel good about your performance and you want the audience to be comfortable watching you perform. Audiences are usually apprehensive about performers who project fear.
To explore how correct posture exudes confidence, pretend that you’re a king or queen. Strut like you own the place. Notice your posture. Now pretend that you’re really sick and that your whole body aches. Doesn’t a ruler move differently than someone who is ill?
It’s possible for a king or queen to be ill, but not in this scenario. A king walks tall, carries himself with great dignity and grace, and glides around the room. A sickly person can barely stand, much less project confidence.
In this scenario, which one are you? Are you the king with a dignified posture, or are you stooped and closed off from the world? You’re probably somewhere in the middle. Strive to be the king or queen when you sing.
